Fix two XBZRLE corruption issues
Push zero'd pages into the XBZRLE cache
A page that was cached by XBZRLE, zero'd and then XBZRLE'd again
was being compared against a stale cache value
Don't use 'qemu_put_buffer_async' to put pages from the XBZRLE cache
Since the cache might change before the data hits the wire
